Rapid and incomprehensible talk (6)

I believe the answer is:

babble

'rapid and incomprehensible talk' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for babble that I've seen before include "Prattle" , "Meaningless noise" , "Rabbit on" , "Chatter in thoughtless way - like brook?" , "Utter gibberish" .)

I've seen this clue in the Irish Times (Simplex) and The Irish Times.
